Seems i get swabbed regularly. Once in GSO a buddy and I had the same flight time going different places. Like 5:30 am and they pulled us both and swabbed us? We were talking before we went to our gates and decided they must have a quota a day and easier to get it over early. Another time leaving Ilion NY with a group of 5. Our last stop had been the underground range, so we obviously all tested positive. Seemed strange to me since at that time probably 80% of the traffic through that airport were Remington employees going to or from the plant. When we opened the plant in Huntsville, I was there monthy. Once they found out I was a Remington employee, they would just wave me through, no bag check, no take off belt and shoes, just welcome to Huntsville.
edit to add: I was not traveling with firearms, we always shipped them ahead via UPS to avoid any hassle. Had plenty of dumb ass management types that thought the rules did not apply to them (since they worked for Remington) and attempt to board with a firearm. They were not usually long with the company. But with myself and armorers, they have found misc. ammo from shoots shows, etc. They always just confiscated, I said "Sorry" and no big deal.
